java - Bouncy CaSTLe - 如何使用 Bouncy CaSTLe 实现 SignedAndEnveloped 数据

Question

我想创建一个使用 Bouncy CaSTLe(版本 1.59)实现的 signedAndEnvelopedData (PKCS #7) 数据。

在 Bouncy CaSTLe 中，接口(interface) CMSObjectIdentifiers 包含类型 signedAndEnvelopedData。

但是多次尝试都无法正确创建。能否请您提出一些建议，以下是我实现的核心

1. 首先签署数据

CMSTypedData msg = (CMSTypedData) new CMSProcessableByteArray(
        new ASN1ObjectIdentifier(CMSObjectIdentifiers.data.getId()),
        srcMsg.getBytes(charSet));

Store certs = new JcaCertStore(certList);

CMSSignedDataGenerator gen = new CMSSignedDataGenerator();
ContentSigner signer = new JcaContentSignerBuilder(
        signatureSchema).setProvider("BC").build(privateKey);

gen.addSignerInfoGenerator(new JcaSignerInfoGeneratorBuilder(
        new JcaDigestCalculatorProviderBuilder().setProvider("BC")
                .build()).build(signer, cerx509));

gen.addCertificates(certs);

CMSSignedData sigData = gen.generate(msg, true);
sigData = new CMSSignedData(msg,sigData.getEncoded())

return sigData.getEncoded()

这里我将输入数据设置为 CMSTypeData 作为 CMSObjectIdentifiers.data.getId()

CMSTypedData msg = (CMSTypedData) new CMSProcessableByteArray(
                new ASN1ObjectIdentifier(CMSObjectIdentifiers.data.getId()),
                srcMsg.getBytes(charSet)); 

1. 签名数据的输出将用作包络的输入

CMSTypedData msg = new CMSProcessableByteArray(new ASN1ObjectIdentifier(CMSObjectIdentifiers.signedAndEnvelopedData.getId()),srcMsg.getBytes(charSet));

    CMSEnvelopedDataGenerator edGen = new CMSEnvelopedDataGenerator();

    JcaAlgorithmParametersConverter paramsConverter = new JcaAlgorithmParametersConverter();

    edGen.addRecipientInfoGenerator(
            new JceKeyTransRecipientInfoGenerator(cert,paramsConverter.getAlgorithmIdentifier(PKCSObjectIdentifiers.id_RSAES_OAEP,OAEPParameterSpec.DEFAULT))
                    .setProvider(new BouncyCastleProvider()));
    OutputEncryptor encryptor = new JceCMSContentEncryptorBuilder(CMSAlgorithm.AES256_CBC)
            .setProvider(new BouncyCastleProvider())
            .build()
    CMSEnvelopedData ed = edGen.generate(msg,encryptor)

    encryptedContent = ed.getEncoded()
    String result = new String(Base64.encode(ed.getEncoded()));

    return result;

这里我将输入数据设置为 CMSTypedData 作为 CMSObjectIdentifiers.signedAndEnvelopedData.getId()

CMSTypedData msg = new CMSProcessableByteArray(new ASN1ObjectIdentifier(CMSObjectIdentifiers.signedAndEnvelopedData.getId()),srcMsg.getBytes(charSet));

问题:

1. Bouncy CaSTLe (1.59) 是否支持 PKCS#7 SignedAndEnevloped
2. 如果第一个问题是"is"，我创建 SignedAndEnevloped 数据的步骤是否正确？
3. 如果第一个问题是否定的，有什么方法可以实现吗？

我刚刚写了一个关于使用 Bouncy Caslte Provider 在 XMLSignatrure(SignedAndEnevloped) 中执行 RSA 的演示，请参阅这篇文章，https://honwhy.wang/2018/09/07/use-bc-provider-xmlsignature/

演示代码，

也许您需要调整一些线路以满足您的要求。
